July 3, 2015:
FIA's EVALIDAtor tool is experiencing periodic outages. FIA and the Forest Service CIO are working to fix this problem. We apologize for any inconvenience.
June 16, 2015:
The ratio estimate option (i.e. the option to choose a denominator) is returning incorrect estimates for any ratio involving net growth, mortality, or removals on timberland. Ratio estimates involving net growth, mortality, or removals on forest land are working correctly. Ratio estimates are intended to be restricted to timberland-to-timberland or forest land-to-forest land observations but the restriction is currently malfunctioning for timberland-to-timberland observations. Users may add the following to the numerator and denominator filter boxes to correct for the problem and obtain correct estimates for timberland-to-timberland ratios: and pcond.cond_status_cd = 1 and pcond.reservcd = 0 and pcond.siteclcd in (1,2,3,4,5,6) and cond.cond_status_cd = 1 and cond.reservcd = 0 and cond.siteclcd in (1,2,3,4,5,6).
We are working on the problem and will update the user alert when it is resolved.
The EVALIDator is unable to produce estimates of growth, removals and mortality for multiple inventories when "Trend analysis" is chosen as the row classification variable and the inventories chosen have different sampling designs (i.e., a mix of periodic and annual inventories). In the event that a user inadvertently runs such a retrieval the EVALIDator will return zeroes for the periodic inventories and the correct numbers for the annual inventories. We are sorry for any inconvenience.
FIADB was updated in June 2014 to include the new updated interpretation of the definition of reserved status. All annual data was reanalyzed in accordance with this interpretation and some previously published values have changed as a result. Change estimates were recomputed to account for any modifications. For more details please consult the FIADB User's Guide (http://www.fia.fs.fed.us/library/database-documentation/).
